Description

Technical Field

[0001] This application relates to the technical field of garden maintenance, and in particular to a breathable device for the soil around tree roots. Background Technology

[0002] Ancient and famous trees usually carry a long history and a splendid culture, and are known as living cultural relics. As an important part of trees, the root system is of great significance to their growth and development. Due to the long lifespan of ancient and famous trees, the soil around them is usually compacted, resulting in poor aeration, which can easily affect the normal growth of ancient and famous trees.

[0003] Chinese patent CN207269433U discloses a device for drilling ventilation holes in the roots of ancient and famous trees. It is equipped with a support rod, a handle, a motor and a spiral cutter disc. The maintenance personnel support the spiral cutter disc on the ground with the support rod, and then push the spiral cutter disc down by holding the handle. Driven by the motor, the spiral cutter disc can drill ventilation holes in the ground to make it easier for the tree roots to breathe.

[0004] Although the above solution creates ventilation holes in the compacted soil, these holes are blind holes, resulting in poor airflow within them. This reduces the air exchange effect and thus diminishes the promoting effect of the ventilation holes on root respiration. Summary of the Invention

[0005] In order to improve the ventilation effect of the vents and enhance their effect on promoting the respiration of tree roots, this application provides a ventilation device for the soil around tree roots.

When the soil sampling drill block moves to the bottom end of the vertical drilling pipe, the bottom wall of the groove can push the adjusting block to swing, so that the adjusting block can drive the soil sampling drill block to open the bottom end of the vertical drilling pipe. When the soil sampling drill block gradually moves into the vertical drilling pipe, the bottom end of the vertical drilling pipe can push the soil sampling drill block to gradually close the bottom end of the vertical drilling pipe.

[0019] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0020] This application discloses an aeration device for the soil around tree roots. (See also...) Figure 1 A tree root soil aeration device includes a support plate 1 supported on the ground, a vertical drilling mechanism on the support plate 1 for vertical drilling, and a rotating ring 11 rotatably connected to the edge of the support plate 1. The rotating ring 11 is equipped with an oblique drilling mechanism for oblique drilling from different directions.

[0021] Reference Figure 2 and Figure 3 The vertical drilling mechanism includes a vertical drilling pipe 2, a power component 3, a soil extraction component 4, and a connecting component 5.

[0022] The vertical drilling pipe 2 is set vertically. The horizontal cross-section of the outer wall of the vertical drilling pipe 2 is circular, and the horizontal cross-section of the inner wall of the vertical drilling pipe 2 is rectangular. The vertical drilling pipe 2 is connected to the support plate 1 through the power component 3. The power component 3 is used to drive the vertical drilling pipe 2 to rotate and move downward, so as to drive the vertical drilling pipe 2 to drill vertically in the soil layer. The soil sampling component 4 includes four corresponding soil sampling drill blocks 41 and a sampling part 42. The soil sampling drill blocks 41 correspond to the four inner walls of the vertical drilling pipe 2.

[0023] Reference Figure 3The soil sampling drill block 41 is connected to the inner wall of the vertical drilling pipe 2 via the extraction part 42. The extraction part 42 is used to drive the soil sampling drill block 41 to move up and down along the inner wall of the vertical drilling pipe 2. When the soil sampling drill block 41 moves down, it can adjust its position to the bottom of the vertical drilling pipe 2. When the soil sampling drill block 41 moves up, it can push the soil in the vertical drilling pipe 2 out of the vertical drilling pipe 2.

[0024] The extraction part 42 is used to open the bottom end of the vertical drilling pipe 2 when the soil sampling drill block 41 is located at the bottom end of the vertical drilling pipe 2. On the one hand, soil can enter the vertical drilling pipe 2, and on the other hand, the soil sampling drill block 41 can act as drill teeth to break through the soil layer, which is conducive to the vertical drilling pipe 2 quickly entering the soil layer. The extraction part 42 is used to gradually close the bottom end of the vertical drilling pipe 2 when the soil sampling drill block 41 begins to move into the interior of the vertical drilling pipe 2. The four soil sampling drill blocks 41 can completely close the bottom end of the vertical drilling pipe 2 so as to push out all the soil in the vertical drilling pipe 2.

[0025] Reference Figure 3 and Figure 4 The connecting component 5 includes a connecting telescopic rod 51, which is fixedly connected to one of the soil sampling blocks 41. The connecting telescopic rod 51 is used to penetrate into the soil layer around the vertical drilling pipe 2 through the connecting hole 21 opened on the side wall of the vertical drilling pipe 2, so that the hole wall drilled by the vertical drilling pipe 2 can be opened.

[0026] Reference Figure 2 The oblique drilling mechanism includes an oblique support plate 7 and a drilling assembly 8.

[0027] The inclined support plate 7 is fixedly connected to the rotating ring 11 at an incline. The drilling assembly 8 includes a spiral drill rod 81 and a power unit 82. The spiral drill rod 81 is connected to the inclined support plate 7 through the power unit 82. The bottom end of the spiral drill rod 81 is located close to the vertical drilling pipe 2. The power unit 82 is used to drive the spiral drill rod 81 to drill obliquely into the soil layer. The spiral drill rod 81 is used to drill obliquely and discharge the soil in the hole.

[0028] Among them, reference Figure 2 and Figure 4 The telescopic rod 51 can be inserted through the connecting hole 21 to the bottom of the hole drilled by the auger rod 81, so that the hole drilled by the vertical drilling pipe 2 can be connected with the hole drilled by the auger rod 81.

[0029] When in use, the ventilation device is moved to the preset drilling position of the tree root system. The extraction part 42 drives the soil-taking drill block 41 to move to the bottom of the vertical drilling pipe 2. On the one hand, the soil can enter the vertical drilling pipe 2, and on the other hand, the soil-taking drill block 41 can quickly break the soil layer. The power component 3 can drive the vertical drilling pipe 2 to rotate and move downward. During the rotation and downward movement, the vertical drilling pipe 2 opens vertical holes in the soil layer for ventilation and allows the soil in the holes to enter its own interior.

[0030] The extraction unit 42 can drive the soil sampling drill block 41 to move upward and move the soil sampling drill block 41 into the vertical drilling pipe 2. All the soil sampling drill blocks 41 together push the soil upward along the vertical drilling pipe 2, so that the soil in the vertical drilling pipe 2 can be discharged from the hole without the vertical drilling pipe 2 being removed from the soil layer.

[0031] Rotate the rotating ring 11 to adjust the position of the inclined support plate 7 so that the spiral drill rod 81 can be moved to the position of inclined drilling. The power unit 82 drives the spiral drill rod 81 to drill into the soil layer at an angle. While drilling, the spiral drill rod 81 discharges the soil in the hole and opens an inclined hole in the soil layer for ventilation.

[0032] Because the bottom end of the auger rod 81 is located close to the vertical drilling pipe 2, the bottom end of the inclined hole can be close to the vertical hole, reducing the shortest distance between the vertical hole and the inclined hole. When the soil sampling drill block 41 moves the connecting telescopic rod 51 to the connecting hole 21, the movement of the soil sampling drill block 41 is stopped, and the connecting telescopic rod 51 extends out. The connecting telescopic rod 51 can pass through the connecting hole 21 to the bottom end of the inclined hole, so that the inclined hole and the vertical hole can be connected to each other. After the connecting telescopic rod 51 retracts, the soil sampling drill block 41 is moved again.

[0033] Based on the above analysis, vertical holes can be opened by the vertical drilling pipe 2 and the soil sampling drill block 41, and oblique holes with their bottom ends close to the vertical holes can be opened by the spiral drill rod 81. The vertical holes and oblique holes can be connected by the connecting telescopic rod 51 and the connecting hole 21, so that air can flow between the vertical holes and the oblique holes, improving the ventilation effect of the ventilation holes and thus enhancing the effect of the ventilation holes on the respiration of tree roots.

[0034] It should be noted that, referring to Figure 1 The support plate 1 can be supported on the ground by a fixed bracket or a movable bracket. Both fixed brackets and movable brackets are existing technologies. In this embodiment, in order to facilitate the movement of the ventilation device, the support plate 1 is supported on the ground by a mobile trolley.

[0035] In this embodiment, refer to Figure 2 In order to fix the position of the oblique drilling mechanism during drilling, multiple fixing holes 13 are evenly opened near the edge of the support plate 1. The angle between the center of two adjacent fixing holes 13 and the line connecting the rotation center of the rotating ring 11 is no more than 10 degrees. Multiple fixing bolts 14 are slidably passed through the rotating ring 11, and each fixing bolt 14 is used to be threaded into the fixing hole 13.

[0036] Specifically, refer to Figure 3The extraction unit 42 includes a soil extraction rod 421. The soil extraction rod 421 is slidably disposed on the inner wall of the vertical drilling pipe 2 with a dovetail block and dovetail groove structure, and the sliding direction is vertical. The bottom end of the soil extraction rod 421 is connected to the soil extraction drill block 41. A first motor 422 is connected to the side of the soil extraction rod 421 near the inner wall of the vertical drilling pipe 2. The first motor 422 is fixed to the outer wall of the vertical drilling pipe 2 and is used to drive the soil extraction rod 421 to slide up and down.

[0037] In this embodiment, a rack 425 is fixedly connected to the side of the soil sampling rod 421 near the inner wall of the vertical drilling pipe 2. The rack 425 meshes with a first gear 426. The first gear 426 is rotatably connected to the outer wall of the vertical drilling pipe 2. The vertical drilling pipe 2 has a meshing notch 25 for the first gear 426 and the rack 425 to mesh. The output shaft of the first motor 422 is fixedly connected to the first gear 426. The first gear 426 and the rack 425 realize the transmission connection between the first motor 422 and the soil sampling rod 421.

[0038] The first motor 422 can drive the soil sampling rod 421 to slide up and down through the first gear 426 and rack 425, so that the soil sampling rod 421 can drive the soil sampling drill block 41 to move up and down, thereby allowing the soil sampling drill block 41 to move down as drill teeth and move up to discharge soil.

[0039] Furthermore, referring to Figure 4 An adjusting shaft 423 is fixedly connected to the bottom end of the soil sampling rod 421. The adjusting shaft 423 is rotatably mounted on the soil sampling drill block 41. An adjusting block 424 is fixedly connected to the soil sampling drill block 41. The adjusting block 424 is slidably mounted in a groove 22 opened on the inner wall of the vertical drilling pipe 2. When the soil sampling drill block 41 moves to the bottom end of the vertical drilling pipe 2, the bottom wall of the groove 22 can push the adjusting block 424 to swing, so that the adjusting block 424 can drive the soil sampling drill block 41 to open the bottom end of the vertical drilling pipe 2. When the soil sampling drill block 41 gradually moves into the vertical drilling pipe 2, the bottom end of the vertical drilling pipe 2 can push the soil sampling drill block 41 to gradually close the bottom end of the vertical drilling pipe 2.

[0040] In this embodiment, the rack 425 is also slidably disposed within the groove 22.

[0041] The soil sampling rod 421 forms a hinge structure with the soil sampling drill block 41 through the adjusting shaft 423. When the soil sampling rod 421 drives the soil sampling drill block 41 to move to the bottom end of the vertical drilling pipe 2, the bottom wall of the slide groove 22 can push the adjusting block 424 to swing, so that the adjusting block 424 can drive the soil sampling drill block 41 to swing, so that the side of the soil sampling drill block 41 that was originally abutting against the side wall of the vertical drilling pipe 2 can abut against the bottom end of the vertical drilling pipe 2, thereby making the soil sampling drill block 41 vertically downward as a whole for use as a drill tooth.

[0042] After the vertical drilling pipe 2 completes drilling, the soil sampling rod 421 can drive the soil sampling drill block 41 to move upward. The edge between the side wall and the bottom end of the vertical drilling pipe 2 can drive the soil sampling drill block 41 to swing in the opposite direction. The sliding groove 22 pushes the swing angle of the adjusting block 424 to reduce synchronously, so that all the soil sampling drill blocks 41 can be gathered together and the bottom end of the vertical drilling pipe 2 is closed. The soil sampling drill block 41 continues to move upward in the vertical drilling pipe 2 to push the soil out of the vertical drilling pipe 2.

[0043] Reference Figure 4 In order to facilitate the extension of the connecting telescopic rod 51, the fixed end of the connecting telescopic rod 51 is fixedly inserted into the soil sampling block 41. The rodless cavity of the connecting telescopic rod 51 is fixedly equipped with a second motor 52. The output shaft of the second motor 52 is fixedly connected to a screw 53. The screw 53 is threaded through the movable end of the connecting telescopic rod 51. The movable end of the connecting telescopic rod 51 can only slide relative to the fixed end.

[0044] In this embodiment, the fixed end and the movable end of the connecting telescopic rod 51 are both rectangular in cross-section along the telescopic direction, so that the movable end of the connecting telescopic rod 51 can only slide relative to the fixed end.

[0045] When the connecting telescopic rod 51 moves to the connecting hole 21, the second motor 52 drives the screw 53 to rotate. Since the movable end of the connecting telescopic rod 51 can only slide relative to the fixed end, the screw 53 can drive the movable end of the connecting telescopic rod 51 to slide relative to the fixed end through the threaded transmission, so that the movable end of the connecting telescopic rod 51 can pass through the connecting hole 21 and penetrate into the soil layer.

[0046] Reference Figure 3 Since the soil inside the vertical drilling pipe 2 is relatively dense, in order to facilitate the discharge of the soil inside the vertical drilling pipe 2, the vertical drilling mechanism also includes a soil loosening component 6. The soil loosening component 6 includes a third motor 61 and a spiral drill bit 62. The third motor 61 is mounted on the power component 3, and the output shaft of the third motor 61 is fixedly connected to the spiral drill bit 62, which is located at the top of the vertical drilling pipe 2.

[0047] The third motor 61 can drive the auger drill bit 62 to rotate. The auger drill bit 62 can perform auger drilling on the soil that has moved to the top of the vertical pipe 2, so that the originally dense soil in the vertical pipe 2 can be transformed into a loose state, thus making it easier to discharge the soil in the vertical pipe 2.

[0048] Specifically, refer to Figure 2 and Figure 3 The power assembly 3 includes a first power cylinder 31 and a fourth motor 32. The first power cylinder 31 is fixedly connected to the support plate 1. The movable end of the first power cylinder 31 slides through the support plate 1. The movable end of the first power cylinder 31 is connected to the fourth motor 32. The output shaft of the fourth motor 32 is connected to the vertical striking tube 2 for transmission. The fourth motor 32 is used to drive the vertical striking tube 2 to rotate.

[0049] In this embodiment, the first power cylinder 31 is a hydraulic cylinder, and a connecting plate 33 is fixedly connected to the movable end of the first power cylinder 31. The vertical striking tube 2 is rotatably connected to the connecting plate 33. The fourth motor 32 is fixedly connected to the connecting plate 33 to achieve connection with the movable end of the first power cylinder 31. The output shaft of the fourth motor 32 is fixedly connected to the second gear 34, and the second gear 34 meshes with a gear ring 35. The gear ring 35 is fixedly sleeved on the vertical striking tube 2. The second gear 34 and the gear ring 35 realize the transmission connection between the output shaft of the fourth motor 32 and the vertical striking tube 2.

[0050] The first power cylinder 31 can drive the vertical drilling pipe 2 and the fourth motor 32 to move downward through the connecting plate 33, so that the vertical drilling pipe 2 can be inserted into the soil layer. The fourth motor 32 can drive the vertical drilling pipe 2 to rotate through the second gear 34 and the gear ring 35, so that the vertical drilling pipe 2 can rotate while moving downward, thereby making it easier for the vertical drilling pipe 2 to drill holes.

[0051] Specifically, refer to Figure 2 The power unit 82 includes a second power cylinder 821 and a fifth motor 822. The second power cylinder 821 is fixedly connected to the inclined support plate 7. The movable end of the second power cylinder 821 is fixedly connected to a sliding seat 823. The sliding seat 823 is slidably connected to the inclined support plate 7. The fifth motor 822 is fixedly connected to the sliding seat 823. The output shaft of the fifth motor 822 is fixedly connected to the spiral drill rod 81.

[0052] In this embodiment, the second power cylinder 821 is a hydraulic cylinder.

[0053] The second power cylinder 821 can drive the sliding seat 823 to slide along the inclined support plate 7. The sliding seat 823 can drive the fifth motor 822 and the spiral drill rod 81 to slide. The fifth motor 822 can drive the spiral drill rod 81 to rotate, so that the spiral drill rod 81 can drill into the soil layer at an angle. The spiral drill rod 81 can make a hole in the soil layer and can discharge the soil from the hole.

[0054] Reference Figure 2 and Figure 5 In order to facilitate the collection of soil discharged by the spiral drill rod 81, the inclined drilling mechanism also includes a soil sampling sleeve 9. The soil sampling sleeve 9 is connected to the inclined support plate 7. The spiral drill rod 81 is used to drill into the soil layer through the soil sampling sleeve 9. The lower part of the top of the soil sampling sleeve 9 is connected to a soil discharge port 91. The soil discharge port 91 is detachably connected to a first soil bag 92.

[0055] In this embodiment, the soil-collecting sleeve 9 is slidably connected to the inclined support plate 7 along the extension and retraction direction of the second power cylinder 821. A third power cylinder 94 is provided between the soil-collecting sleeve 9 and the inclined support plate 7. The third power cylinder 94 is a hydraulic cylinder and is fixedly connected to the inclined support plate 7. The movable end of the third power cylinder 94 is fixedly connected to the soil-collecting sleeve 9. The third power cylinder 94 can drive the soil-collecting sleeve 9 to move closer to or away from the ground, so that the soil-collecting sleeve 9 does not easily obstruct the movement of the ventilation device. In this embodiment, the first soil bag 92 and the soil discharge port 91 are detachably connected by a clamp.

[0056] The soil discharged from the auger rod 81 can enter the soil sampling sleeve 9. Because the soil sampling sleeve 9 is set at an inclination, when the soil moves to the top of the soil sampling sleeve 9, the soil can be discharged from the discharge port 91 into the first soil bag 92 under the action of gravity, making it easy to collect the soil discharged from the auger rod 81.

[0057] Reference Figure 2 In order to facilitate the collection of soil discharged from the vertical pipe 2, the top of the vertical pipe 2 is sealed, and a soil inlet 23 is connected to the side wall of the top. The soil inlet 23 is detachably connected to a second soil bag 24. In this embodiment, the soil inlet 23 and the second soil bag 24 are detachably connected by a clamp.

[0058] The soil at the top of the vertical pipe 2 can be discharged from the soil outlet 23 into the second soil bag 24, making it easy to collect the soil discharged from the vertical pipe 2.

[0059] Reference Figure 2 and Figure 5 To prevent the holes drilled by the vertical drilling pipe 2 and the auger drill rod 81 from being blocked, a packing box 12 is fixedly connected to the support plate 1. The packing box 12 is filled with breathable packing. The packing box 12 is connected to a first packing pipe 121 and a second packing pipe 122. Both the first packing pipe 121 and the second packing pipe 122 are controlled by valves to open and close. The first packing pipe 121 is used to connect with the feed inlet 93 at the top of the soil sampling sleeve 9, and the second packing pipe 122 is used to connect with the soil inlet 23.

[0060] In this embodiment, the breathable filler is a mixture of humus and perlite. In this embodiment, the first filler pipe 121 is connected to the inlet 93 and the second filler pipe 122 is connected to the soil inlet 23 by clamps. The second filler pipe 122 needs to be disassembled from the second soil bag 24 before it can be connected to the soil inlet 23.

[0061] After the auger rod 81 discharges all the soil, the first packing pipe 121 is connected to the feed inlet 93 by a clamp, and the valve on the first packing pipe 121 is opened to make the auger rod 81 rotate in the opposite direction. The auger rod 81 is slowly pulled out of the inclined hole. While the auger rod 81 is moving out of the inclined hole, it pushes the breathable packing to continuously fill the inclined hole so that the inclined hole is not easily blocked while maintaining its breathability.

[0062] After the soil in the vertical drilling pipe 2 is discharged, the soil sampling drill block 41 is moved back to the bottom of the vertical drilling pipe 2. The second soil bag 24 on the soil inlet 23 is removed, and the second filling pipe 122 is connected to the soil inlet 23 by a clamp. The valve on the second filling pipe 122 is opened, and the vertical drilling pipe 2 is slowly pulled out of the vertical hole. While the vertical drilling pipe 2 is being moved out of the vertical hole, the breathable filling material can be continuously filled into the vertical hole so that the vertical hole is not easily blocked while maintaining its breathability.

[0063] The implementation principle of the tree root soil aeration device in this application embodiment is as follows: In use, the first power cylinder 31 and the fourth motor 32 cooperate to drive the vertical drilling pipe 2 to drill vertical holes in the ground. After drilling vertical holes, the first motor 422 drives the soil sampling rod 421 to push the soil sampling drill block 41 to discharge soil from the vertical drilling pipe 2. The second power cylinder 821 and the fifth motor 822 cooperate to drive the spiral drill rod 81 to drill oblique holes in the ground. The spiral drill rod 81 discharges soil during drilling. When the connecting telescopic rod 51 moves to the connecting hole 21, the second motor 52 drives the screw 53 to extend the connecting telescopic rod 51. The connecting telescopic rod 51 can pass through the connecting hole 21 into the oblique hole, so that the vertical hole and the oblique hole can be connected. This allows the air between the vertical hole and the oblique hole to flow between each other, improving the ventilation effect of the aeration hole and thus enhancing the promoting effect of the aeration hole on the respiration of tree roots.

[0064] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
